Question

1/5 +1/5+1/5+1/5=4*()​

Answer 1

Answer:

4/5

Step-by-step explanation:

1/5+1/5+1/5+1/5=4*1/5

Multiplication is repeated addition

Answer 2

Correct Question:-

Find the value of x

${ \bf{ \frac{1}{5 } + \frac{1}{5} + \frac{1}{5} + \frac{1}{5} = 4 \times x}}$

Solution:-

If denominators are same, then such fractions are said to be like fractions and can be added directly. by keeping the denominators of the fractions common.

Now,

${ \dashrightarrow {\bf{ \frac{1}{5 } + \frac{1}{5} + \frac{1}{5} + \frac{1}{5} = 4 \times x}}}$

${ \dashrightarrow {\bf{ \frac{1 + 1 + 1 + 1 }{5} = 4 \times x}}}$

${ \dashrightarrow {\bf{ \frac{4 }{5} = 4 \times x}\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \gray{i.e.}}} }$

${ \dashrightarrow {\bf{ x = \frac{4 }{5 \times 4} }} }$

${ \dashrightarrow {\bf{ x = { \cancel{\frac{4 }{20} }} = { \cancel{\frac{1}{5}}} = 0.2 }} }$

Hence value of x is 0.2 or 1/5

{ Note:- if the denominators are different, (such fractions are called unlike fractions) then we need to rationalise the denominators and then add the numerators }
